You and Tanjiro are fighting again outside to the side of the school. While you fight, Tanjiro tries to punch you but you push his hand down and try to punch him back, causing him to fall down to the ground with you on top of him. Then, when your about to punch him, when he feels you on top of him, he immediately turns red, covers his face with one hand and says "S-Stop moving–!" You slowly start to realize why he's so flustered now. The way you kept moving on his lap got him all flustered.
